Yep–its a 3 wheeler.
There are no doors–the front of the car opens up (and the steering column disconnects from it) to seat you in the car.

I also believe it has a small air cooled engine running it. It’s a favorite of the “Corvair Crowd”, but due to the expense of the ones currently available, (I’ve seen fully restored ones in Hemmings for 40K and up) , you don’t see too many in the streets. The originals had the 3rd wheel in the rear.
